Find the inverse of each given functions.<br> f(x) = 4x − 12
Paha777 [63]

Answer:

y=1/4x+3

Step-by-step explanation:

To find the inverse, switch x and y or f(x)

f(x)=4x-12

y=4x-12

x=4y-12

Add 12 to both sides

x+12=4y-12+12

x+12=4y

Divide both sides by 4

x+12/4=y

1/4x+12/4=y

1/4x+3=y

y=1/4x+3

Y=x+2 y=-3X <br><br>solve system of equations algebraically <br>​
goblinko [34]

Answer:

(x,y) = -1/2 , 3/2

Step-by-step explanation:

Let y = x +2 ----- (1)

y = -3x ------ (2)

Put equal both sides x +2 = -3x

x = -3x -2

x +3x = -2

4x = -2

x = -1/2 Put it in 2nd equation

Y = -3 (-1/2)

y = 3/2

so (x,y) = -1/2 , 3/2

Hope you got it.
